BACKGROUND

1. Field

The present invention relates to a top chassis and a display device having the same.

2. Description of the Related Art

Various display devices such as liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays include a display panel which includes a pixel region. High surface quality of the pixel region of the display panel is desired in all industries. To improve the surface quality of the pixel region, it is important to prevent the display panel from being damaged during the manufacture of a display device and after the completion of the display device.

One way of preventing the display panel from being damaged during the process of manufacturing the display device is to perform the process of manufacturing the display device after a protective film is placed on the surface of the display panel. The protective film placed on the surface of the display panel absorbs shocks that can be applied to the display panel during the process of manufacturing the display panel. Thus, the protective film may be damaged instead of the display panel.

On occasion, after a top chassis is coupled to the display panel, it is not easy to remove the protective film since a base plate of the top chassis is placed on edges of the protective film. Therefore, the protective film is removed before the top chassis is coupled to the display panel, and another protective film is attached onto the top chassis after the completion of the display device in order to prevent the damage of the display panel. The protective film can be arbitrarily removed by a consumer.

SUMMARY

Aspects of the present invention provide a display device which is structured to allow a protective film to be removed easily.

FIG. 1 is an exploded perspective view of a display device 1000 according to an embodiment of the present invention. Referring to FIG. 1, the display device 1000 includes a display panel 200, a protective film 900, and a top chassis 100. The display device 1000 may further include a polarizing film 800, a light source assembly, and a bottom chassis 150.

The display panel 200 is a panel that displays images. Examples of the display panel 200 include a liquid crystal display (LCD) panel, an electrophoretic display panel, an organic light-emitting diode (OLED) panel, a light-emitting diode (LED) panel, an inorganic electroluminescent (EL) display panel, a field emission display (FED) panel, a surface-conduction electron-emitter display (SED) panel, a plasma display panel (PDP), and a cathode ray tube (CRT) display panel. A case where the display device 1000 according to the current embodiment is an LCD will be described below as an example. In addition, a case where the display panel 200 is an LCD panel will be described as an example. However, the display device 1000 and the display panel 200 according to the present invention are not limited to these examples, and various types of display devices and display panels can be used as the display device 1000 and the display panel 200.

The display panel 200 may include a first substrate 210, a second substrate 220 which faces the first substrate 210, a liquid crystal layer, and a flexible circuit board 240 which is attached to the first substrate 210.

The first substrate 210 may include a pixel region and a non-pixel region. The pixel region of the first substrate 210 is where images are displayed, and the non-pixel region of the first substrate 210 is where no images are displayed. A driver 230 may be formed in the non-display region of the first substrate 210 to transmit various signals (such as a driving signal) required to display an image in the pixel region.

The pixel region of the first substrate 210 may be overlapped by the second substrate 220. However, the non-pixel region of the first substrate 210 may be exposed without being overlapped by the second substrate 220.

The second substrate 220 may face the first substrate 210. The liquid crystal layer may be located between the first substrate 210 and the second substrate 220. A sealing member such as a sealant may be placed between the first and second substrates 210 and 220 along the periphery of the first and second substrates 210 and 220, thereby bonding the first and second substrates 210 and 220 together.

The first substrate 210 and the second substrate 220 may be rectangular parallelepipeds. Although the first substrate 210 and the second substrate 220 are illustrated in FIG. 1 as being rectangular parallelepipeds for ease of description, their shape can vary according to the shape of the display panel 200.

The flexible circuit board 240 may be attached to the first substrate 210 and may output various signals to the driver 230 of the non-pixel region.

The polarizing film 800 may include a first polarizing film 810 and a second polarizing film 820. Each of the first polarizing film 810 and the second polarizing film 820 may be located directly on the display panel 200. Specifically, the first polarizing film 810 may be on a first surface of the display panel 200, and the second polarizing film 820 may be on a second surface of the display panel 200 which is opposite the first surface of the display panel 200. The first and second surfaces of the display panel 200 may be opposite surfaces which face each other. The first polarizing film 810 and the second polarizing film 820 may be rectangular parallelepipeds. Although the first polarizing film 810 and the second polarizing film 820 are illustrated in FIG. 1 as being rectangular parallelepipeds for ease of description, their shape can vary according to the shape of the display panel 200.

The protective film 900 may be on the second polarizing film 820 to protect the display panel 200 and the second polarizing film 820. Specifically, the protective film 900 may be provided to prevent the display panel 200 and the second polarizing film 820 from being damaged during a process of manufacturing the display device 1000. Also, the protective film 900 may be provided to protect the display panel 200 and the second polarizing film 820 from the external environment after the process of manufacturing the display device 1000. A film detaching member 910 may be attached to an end of the protective film 900. The film detaching member 910 may be used to detach the protective film 900 from the second polarizing film 820. The film detaching member 910 will be described later.

The light source assembly may be located under the display panel 200. The light source assembly may include light source units 500, a light guide plate 600, a reflective sheet 700, one or more optical sheets 300, and a mid frame 400. Each of the light source units 500 includes light sources 520 which emit light and a circuit board 510 on which the light sources 520 are placed. The light guide plate 600 guides light emitted from the light source unit 500. The reflective sheet 700 is located under the light guide plate 600 and changes the path of light proceeding downward from the light guide plate 600. The optical sheets 300 are on the light guide plate 600 and modulate optical characteristics of output light. The mid frame 400 accommodates the light source units 500, the light guide plate 600, the reflective sheet 700, and the optical sheets 300.

In FIG. 1, an edge-type light source assembly in which the light sources 520 are located on sides of the light guide plate 600 is illustrated as an example of the light source assembly. However, the light source assembly is not limited to the edge-type light source assembly. A direct-type light source assembly in which the light sources 520 are located under the light guide plate 600 is also applicable as the light source assembly.

The bottom chassis 150 may accommodate the optical sheets 300, the light guide plate 600, the light source units 500, and the reflective sheet 700. The bottom chassis 150 may be made of a conductive material such as metal.

The display device 1000 may further include the top chassis 100 which covers edges of the display panel 200 and surrounds side surfaces of the display panel 200 and the light source assembly. The top chassis 100 for the display device 1000 according to the current embodiment will now be described in more detail with reference to FIG. 2.

FIG. 2 is a perspective view of the top chassis 100 for the display device 1000 shown in FIG. 1.

The top chassis 100 includes a base plate 130 and a plurality of sidewalls 140 which extends from the base plate 130. The base plate 130 defines a first open surface 110 which exposes the pixel region of the display panel 200 and a second open surface 120 which protrudes from an end of the first open surface 110. Each of the sidewalls 140 may extend from the base plate 130 in a direction, for example, in a vertical direction. Although not shown in FIG. 2, at least one of the sidewalls 140 may include a coupling portion coupled to the mid frame 400.

In FIG. 2, the first open surface 110 is illustrated as being rectangular for ease of description. However, the shape of the first open surface 110 is not limited to the rectangular shape. The first open surface 110 can also have a circular shape or another polygonal shape. In addition, in FIG. 2, an end of the first open surface 110 from which the second open surface 120 protrudes is a vertex of a rectangle. However, the present invention is not limited thereto. The end of the first open surface 110 from which the second open surface 120 protrudes can also be a side of the rectangle or a portion of a side of the rectangle. In addition, edges of the second open surface 120 are illustrated in FIG. 2 as being straight for ease of description. However, the present invention is not limited thereto. The edges of the second open surface 120 can also be curved.

The top chassis 100, the protective film 900 and the film detaching member 910 will now be described in more detail with reference to FIG. 3 which is a plan view of the display device 1000 shown in FIG. 1 and FIG. 4 which is a cross-sectional view of the display device 1000 taken along the line IV-IV′ of FIG. 3.

Referring to FIG. 4, the top chassis 100 may be on the display panel 200 and the protective film 900. The top chassis 100 is on the edges of the display panel 200, that is, the non-pixel region and side surfaces of the mid frame 400. The base plate 130 of the top chassis 100 defines the first open surface 110 which exposes the pixel region and the second open surface 120 which protrudes from an end of the first open surface 110. In the current embodiment, the first open surface 110 is shaped like a rectangle, and an end of the first open surface 110 is a vertex of the rectangle. In addition, the second open surface 120 extends from the open surface 110 with a uniform width. In the current embodiment, the second open surface 120 not only exposes the whole of an end of the protective film 900 which faces the second open surface 120 but also extends further in a direction in which it protrudes from the first open surface 110.

The display device 1000 may further include the film detaching member 910. The film detaching member 910 may be attached to the protective film 900 and may be at least partially exposed through the second open surface 120.

Specifically, the film detaching member 910 may include an adhering portion 911 and a protruding portion 912. The adhering portion 911 of the film detaching member 910 may be attached to an end of the protective film 900. Here, the adhering portion 911 may be attached onto the protective film 900 which faces the second open surface 120. An adhesive layer 960 may be formed between the adhering portion 911 of the film detaching member 910 and the protective film 900. The protruding portion 912 of the film detaching member 910 may extend from the adhering portion 911 in the direction in which the second open surface 120 protrudes. In addition, the protruding portion 912 may extend upward from an end of the adhering portion 911 to contact the base plate 130 of the top chassis 100. Here, the protruding portion 912 and the adhering portion 911 may form an obtuse angle. In addition, at least a portion of the protruding portion 912 may protrude further than a surface of the top chassis 100. Although not shown in FIG. 4, at least a portion of the protruding portion 912 may be attached to the top chassis 100, and an adhesive layer 970 may be formed between the portion of the protruding portion 912 and the top chassis 100.

Since the display device 1000 according to the current embodiment includes the second open surface 120 defined by the top chassis 100, the film detaching member 910 attached to an end of the protective film 900 is exposed, and the protective film 900 can be easily removed using the protruding portion 912 of the film detaching member 910. That is, the protective film 900 used to prevent the display panel 200 from being damaged during the process of manufacturing the display device 1000 does not need to be removed before the top chassis 100 and the display panel 200 are coupled to each other. Instead, the protective film 900 can be arbitrarily removed by a consumer after the completion of the display device 1000. Therefore, a process of removing the protective film 900 during the manufacture of the display device 1000 and a process of attaching another protective film 900 onto the top chassis 100 after the completion of the display device 1000 can be omitted. Accordingly, this can reduce the time required to manufacture the display device 1000. Furthermore, since it is not necessary to attach another protective film 900 onto the top chassis 100, the material cost of the display device 1000 can be saved.

FIG. 5 is a plan view of a display device 2000 according to another embodiment of the present invention. FIG. 6 is a cross-sectional view of the display device 2000 taken along the line VI-VI′ of FIG. 5.

Referring to FIGS. 5 and 6, a base plate 131 of a top chassis defines a first open surface 110 which exposes a pixel region and a second open surface 121 which protrudes from an end of the first open surface 110. The second open surface 121 may protrude from an end of the first open surface 110 only to a distance at which it exposes the whole of an end of a protective film 900 which faces the second open surface 121. Here, when the second open surface 121 protrudes only to a distance at which it exposes the whole of an end of the protective film 900, a longitudinal section of the end of the protective film 900 which faces the second open surface 121 is aligned with a longitudinal section of the second open surface 121, as shown in FIGS. 5 and 6. The second open surface 121 is substantially identical to the second open surface 120 of FIGS. 1 through 4 except that the second open surface 121 protrudes from an end of the first open surface 110 only to a distance at which it exposes the whole of an end of the protective film 900 which faces the second open surface 121, and thus a repetitive description thereof will be omitted.

Referring to FIGS. 7 and 8, a base plate 132 of a top chassis defines a first open surface 110 which exposes a pixel region and a second open surface 122 which protrudes from an end of the first open surface 110. The second open surface 122 may exposes only part of an end of a protective film 900 which faces the second open surface 122. The second open surface 122 is substantially identical to the second open surface 120 of FIGS. 1 through 4 except that the second open surface 122 exposes only part of an end of the protective film 900 which faces the second open surface 122, and thus a repetitive description thereof will be omitted.

In addition, referring to FIGS. 7 and 8, the display device 3000 may further include a film detaching member 930 which is attached to the protective film 900 and is at least partially exposed through the second open surface 122. The film detaching member 930 may include an adhering portion 931 and a protruding portion 932. The protruding portion 932 and the adhering portion 931 may form an acute angle. The film detaching member 930 is substantially identical to the film detaching member 910 of FIGS. 1 through 4 except that the protruding portion 932 and the adhering portion 931 form an acute angle, and thus a repetitive description thereof will be omitted.

The protruding plate 134 b may be shaped like a rectangular parallelepiped plate, and a cross section of the protruding plate 134 b may be shaped like a quadrilateral. However, the present invention is not limited thereto, and the protruding plate 134 b and the cross section of the protruding plate 134 b can have various shapes. The base plate 134 is substantially identical to the base plate 130 of FIGS. 1 through 4 except that the base plate 134 includes the flat plate 134 a ; and the protruding plate 134 b, and thus a repetitive description thereof will be omitted.

In addition, referring to FIGS. 10 and 11, the display device 5000 may further include a film detaching member 940 which is attached to s protective film 900 and is at least partially exposed through the second open surface 124.

Referring to FIGS. 14 and 15, a film detaching member may be integrated with a protective film 905. That is, the protective film 905 may include a panel protecting portion 905 a and a film detaching portion 905 b which is integrated with the panel protecting portion 905 a and protrudes from a surface of the panel protecting portion 905 a.

Embodiments of the present invention provide at least one of the following characteristics.

First of all, a process of removing a protective film used to prevent a display panel from being damaged during a process of manufacturing a display device and a process of attaching another protective film onto a top chassis can be omitted. Accordingly, the time required to manufacture the display device can be reduced.

Furthermore, since it is not necessary to attach another protective film onto the top chassis, the material cost of the display device can be saved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims. It is therefore desired that the present embodiments be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than the foregoing description to indicate the scope of the invention.
